--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
In any case, it would be useful to narrow it to a single CU, if you know
libLLVMCodeGen.so.17 is bad and have trees built by good vs. bad revision, take
the link line of that library, amend all .o objects with absolute paths to the
good objects in a text file, run that + test, then replace second half of the
paths with the ones to bad objects, etc.
